11.1.2 MCCH messages transmission in test
The clause provides rules for MCCH messages transmission for MBMS test.
A whole set of MCCH messages is repeatedly transmitted.
The sending of the whole set of critical MCCH information messages is started at the first TTI of a repetition period if no ACCESS INFORMATION message is sent.
No ACCESS INFORMATION messages shall be transmitted in the modification period unless explicitly mentioned in the Test Procedure or Expected Sequence.
In case an ACCESS INFORMATION message transmission is explicitly mentioned in the test procedure or expected sequence these shall be transmitted starting at the first frame of the second access information period of the modification period, after MBMS MODIFIED SERVICES INFORMATION, unless stated otherwise. If the test case procedure describes more than one ACCESS INFORMATION message in the same modification period, this means that an ACCESS INFORMATION message is transmitted in every access info period from the first message until the end of the modification period, unless stated otherwise.
If an ACCESS INFORMATION message is to be sent in the access information period in a repetition period the critical MCCH messages are transmitted in the next frame after the ACCESS INFORMATION message.
If an ACCESS INFORMATION message is to be sent in the access information period that is not the first access information period in a repetition period,
And if a critical MCCH message is segmented into several RLC PDUs with consecutive sequence numbers and is occasionally, only partially transmitted at the end of the preceding access information period, the remaining RLC PDUs shall be transmitted after ACCESS INFORMATION (as out of sequence delivery) in the next access information period within the repetition period.
If an MBMS service is changed, this will be notified on MICH during one entire modification period before the change occurs. The service should then appear in MBMS MODIFIED SERVICES INFORMATION for one modification period, and then in the next modification period move to MBMS UNMODIFIED SERVICES INFORMATION. The MBMS MODIFIED SERVICES INFORMATION message should be transmitted once per repetition period throughout the modification period. All MCCH messages will contain the same content during and after this service change, except for MBMS MODIFIED SERVICES INFORMATION and MBMS UNMODIFIED SERVICES INFORMATION, unless stated otherwise in the test procedure.
11.1.3 Combinations and transmission order of critical MCCH messages
|
Combination Id |
Ordered message combinations |
comment |
|
C1 |
MBMS MODIFIED SERVICES INFORMATION (empty services_list) + MBMS UNMODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION |
No session ongoing or PTP session ongoing. |
|
C2 |
MBMS MODIFIED SERVICES INFORMATION (empty services_list) + MBMS UNMODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION + MBMS COMMON RB INFORMATION + MBMS CURRENT CELL p-t-m RB INFORMATION |
PTM sessions are ongoing, no service modification and no neighbouring cells are defined |
|
C3 |
MBMS MODIFIED SERVICES INFORMATION (empty services_list) + MBMS UNMODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION + MBMS COMMON RB INFORMATION + MBMS CURRENT CELL p-t-m RB INFORMATION + MBMS NEIGHBOURING CELL p-t-m RB INFORMATION (per neighbouring cell) |
PTM sessions are ongoing, no service modification |
|
C4 |
MBMS MODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION + MBMS COMMON RB INFORMATION + MBMS CURRENT CELL p-t-m RB INFORMATION + MBMS UNMODIFIED SERVICES INFORMATION |
PTM sessions are ongoing or starting, service modification indicated, no neighbouring cells (for one modification period) |
|
C5 |
MBMS MODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION + MBMS COMMON RB INFORMATION + MBMS CURRENT CELL p-t-m RB INFORMATION + MBMS NEIGHBOURING CELL p-t-m RB INFORMATION (per neighbouring cell related to modified services) + MBMS UNMODIFIED SERVICES INFORMATION + MBMS NEIGHBOURING CELL p-t-m RB INFORMATION (per neighbouring cell not related to modified services) |
PTM sessions are ongoing or starting, service modification indicated (for one modification period) |
|
C6 |
MBMS MODIFIED SERVICES INFORMATION (empty services_list) + MBMS UNMODIFIED SERVICES INFORMATION (empty services_list) + MBMS GENERAL INFORMATION |
No MBMS services |
|
C7 |
MBMS MODIFIED SERVICES INFORMATION + MBMS GENERAL INFORMATION + MBMS UNMODIFIED SERVICES INFORMATION |
PTP sessions are starting or another required UE action. MBMS UNMODIFIED SERVICES INFORMATION may or may not contain services. |
NOTE 1: PTM test cases shall use message combinations C2 and C4 by default, according to the rules in clause 11.1.2, unless stated otherwise. If MBMS neighbouring cells are configured in the PTM test case then combinations C3 and C5 shall be used unless stated otherwise. PTP and counting test cases shall use message combinations C6 and C7, unless stated otherwise.
NOTE 2: If combination C6 is used in the initial condition, then the list of services in MBMS UNMODIFIED SERVICES INFORMATION will be empty. Then if any service is modified this will be added to the list, so the list of services will grow during the test (e.g. C6->C4->C2 or C6->C5->C3 or C6->C7->C6). If combination C1 is used in the initial condition then a total of 12 services will always be included in MBMS UNMODIFIED SERVICES INFORMATION and MBMS MODIFIED SERVICES INFORMATION (e.g. C1->C4->C2 or C1->C5->C3 or C1->C7->C6).
